The Apollo Automation PLT-1 is an ESP32-C3-based  indoor plant multisensor that measures soil moisture (capacitive), air temperature, humidity, LUX, and UV, which can be used with Home Assistant via ESPHome!

It also features an onboard piezo buzzer and addressable RGB LED. Soil temperature can be measured using the optional temperature probe add-on. The sensor comes in a battery or non-battery version, with the non-battery (USB-C powered, 5V 1A) version being significantly smaller - select an option before adding to your cart.

The PLT-1 uses a capacitive soil moisture sensor, which offers much better accuracy and durability compared to resistive sensors. Additionally, the ground contact portion is protected with a conformal coating, ensuring longevity and resistance to environmental factors.

Both versions of the PLT-1 come with a 3D printed case.

Note: The PLT-1B (battery version) does not include a battery or charger. You will need to source their own rechargeable 18650 batteries for the battery version, and a charger. Battery life is estimated at 6 months based on a quality rechargeable 18650 and the default sleep / wake settings.

    • Optimising Sunlight Exposure: Use the LUX and UV sensors to monitor light levels, ensuring your plants get the right amount of sunlight. Automate window shades or grow lights based on current light conditions.
    • Temperature & Humidity Management: Track air temperature and humidity with the AHT20-F sensor, adjusting indoor climate controls (like fans, heaters, or humidifiers) to maintain ideal growing conditions.
    • Soil Temperature Monitoring: Use the optional waterproof soil temperature probe to monitor and control soil warmth for temperature-sensitive plants, especially in colder months.
    • Visual & Audio Alerts: The RGB LED can be programmed for visual notifications, such as turning red when soil is dry or green when conditions are optimal. The piezo buzzer can alert you if immediate action is needed.

    Everyday Jeans With A Great Blend
    Size: 32W x 33L, Color: Medium Wash
    These are my new daily drivers. I got the Medium Wash in 32W x 33L, and the size and fit are true to size—a modern slim fit that's not too tight. The key is the stretchiness; there's just enough elastane in the material to make sitting, driving, and bending incredibly comfortable, unlike traditional stiff denim. The softness is immediately noticeable compared to raw denim. For long-term durability, the stretch blend should hold up well with normal wear. The functionality is perfect for casual work environments or weekend outings. Excellent value for a comfortable, stylish jean.

    Sturdy, decent quality jeans!
    Size: 42W x 30L, Color: Dark Blue Vintage
    Excellent jeans. The fit was exactly as expected, the material is stretchy but sturdy. The pictures were accurate including the color, and the price was excellent compared to like items. If you are concerned with branding, there is no external branding on thee jeans, inside the waistband you will "Amazon Essentials" but other than that there is no dicernable marking on the outside of the jeans. I would buy again and would have no issue in reccomending to a family member or a friend.

    Good for the Price
    Size: 38W x 30L, Color: Light Wash
    I wear a 36 x 30 and prefer the slim, stretch fit of these. Not as lightweight as the Buffalo Brand jeans it have, but price is a factor here. They are soft and the length is perfect.
